Delayed genetic effects of habitat fragmentation on the ecologically specialized Florida sand skink (Plestiodon reynoldsi)
Jonathan Q. Richmond, Duncan T. Reid, Kyle G. Ashton, Kelly R. Zamudio
2009, Conservation Genetics (10) 1281-1297
Populations rarely show immediate genetic responses to habitat fragmentation, even in taxa that possess suites of traits known to increase their vulnerability to extinction. Thus conservation geneticists must consider the time scale over which contemporary evolutionary processes operate to accurately portray the effects of habitat isolation. Here, we examine the...

Lee Henry II, A Cheryl Brown Cheryl, J Patrick Clinton Patrick, Patti Hagerty Patti
2009, Report, Classification of regional patterns of environmental drivers and benthic habitats in Pacific Northwest estuaries
Increased anthropogenic nutrient loading and the subsequent eutrophication of coastal ecosystems is a growing ecological and economic problem both in the United States and globally. Eutrophication can result in a range of ecological impacts including hypoxic conditions, fish kills, loss of submerged aquatic vegetation (SAV), degraded benthic conditions, harmful algal blooms, and...
